Description
Factory Cat 5421N is the brush, 18" .028 nylon W/Plate.
It measures 18 inches.
The .028 filament diameter sets how stiff the brush feels in use — thinner filament flexes into the floor surface, thicker filament scrubs harder.
Nylon filament handles general wet and dry scrubbing and keeps its shape through long duty cycles.
Supplied with the mounting plate fitted.
